Title: Photographic silver and vesicular images and a process for their production
Inventor: RINTELEN HARALD VON
IPC: G03C5/60
Filed: 1970-01-05
Abstract: 1278402 Protection of photographic silver and vesicular images AGFA-GEVAERT A G 5 Jan 1970 [7 Jan 1969] 428/70 Heading G2C A process for the production of photographic images composed of a silver image and a vesicular image superimposed imagewise upon the silver image, comprises (i) imagewise exposing a photographic material containing a supported light-sensitive water-permeable silver salt emulsion layer, which contains, dispersed in the said emulsion layer or in another layer arranged on the side thereof furthest from the support, particles of a polymer that are softened or decomposed under heat forming a substantially uniform hydrophobic layer, (ii) photographically processing the exposed material to form a silver image therein, (iii) treating the processed material with a compound that is decomposed by the silver image to form a vesicular image, and (iv) heating the material at a temperature of from 80 to 250‹ C., during or after the formation of the vesicular image so that the originally separated particles combine to form the said hydrophobic layer. The polymer particles preferably have a size from 0À01 to 1Ám. The particles of polymer are preferably present in an amount from 20 to 90% by weight, based on the total amount of binding agent of the layer. The polymer is preferably a copolymer of styrene and butadiene; polyethylene; polyvinylidene chloride; or an alkyl- or aryl-silicone resin. In step (iii) the material is preferably first treated with hydrogen peroxide vapour and then with water vapour at 50 to 90‹C. from 1 to 5 seconds. The water vapour may contain ammonia or the vapour of a volatile amine. The layer containing the developed silver image may be coated with a layer containing hydrogen peroxide which is dried when the material is heated, or the developed material may be contacted with a solution of hydrogen peroxide. The advantage of this process is the high light sensitivity of the silver halide emulsion compared with the poor light sensitivity of known materials giving vesicular images. Also the silver image is intensified by this process. Reference is made to Specification 1196200.

Title: Mechanism for adjusting the commencement of delivery of the fuel injection pump of an injection type internal combustion engine
IPC: F02D1/00
Filed: 1957-01-04
Abstract: 797,188. Starting. KLOCKNER-HUMBOLDT-DEUTZ AKT.-GES. Jan. 4, 1957 [Jan. 7, 1956], No. 429/57. Class 7(5) [Also in Group XXIV] In a timing mechanism for driving the fuel pump of an injection type internal combustion engine wherein the relative angular positions of the crankshaft and fuel pump crankshaft are determined by a centrifugal weight, the mechanism includes means operating on the weight to advance the commencement of the fuel delivery for starting purposes. A gear 4 driven from the engine crankshaft has a coupling element 6 secured by bolts 15 and carrying an adjustable slide block 12 which bears at its sloping flank 10 against the corresponding flank 8 of a centrifugal weight 1. The weight is loaded by a spring 14 and has a second flank 9 bearing on a sloping flank 11 of a second coupling element 7 having a hub 17 shrunk on a shaft 3 coupled at 2 to the fuel pump camshaft drive. The coupling elements 6, 7 are loaded by a spring 13 to bear on the weight 1 which, under centrifugal force on rotation of the coupling moves the coupling elements 6, 7 to vary the relative angular positions of the gear 4 and the shaft 3 to advance the fuel pump timing. To aid engine starting the weight 1 can be moved outwards by a pin 19 co-operating with a sloping face 27 on a slide bolt 20 moved axially through a cross-member 21, control sleeve 22, fork 23 and shart 24. The shaft 24 carries a spring-loaded arm for manual advance of the timing for starting, which arm is returned, to allow whole movement of the weight 1 by the spring when the engine is running. In a modification the weight may be moved for starting by a camming action in the drive from gear 4 to shaft 3, this action being over-ridden by engine oil pressure when the engine has started; the weight may be moved by a bellows acting through linkwork, the bellows rendering the linkwork inoperative on the attainment of a predetermined engine temperature; or the weight may be moved outwards under cold conditions by an arcuate bi-metallic strip, which contracts on the attainment of engine temperature to allow full movement of the weight.

The boron- and fluorine-containing compound may be a fluoborate of NH4, K, Na, Li, Cd, Pb, Ba, Cu, Sn, Ni, or Zn, or a reaction product of a fluoborate with an amine such as mono-ethanolamine, tri-ethanolamine or diethylene tri-amine.  In p the case of complexes represented by X.HF.BF3 or X.BF3 the carrier substance represented by X is selected with consideration for other properties such as lubrication or wetting.  Among such carriers are diethyleneglycol oleate, butyl stearateacetamide, N-hexyl ether, 4,5-dihydro-1,4, diphenyl - 3,5 - phenylamino - 1,2,4 - triazole, pyridine, octyl amine, morpholine, dioxane, aniline, urea, oleic, linoleic or linolic acid, lard oil, polybutene, butyl acetyl ricinoleate, cetyl alcohol, tallow, diethylenetriamine or an oxazoline.  When the compound is added to a grease, good results are obtained if the BF3 or BF4 content of the final mixture is above 0.001 per cent by weight.  If added to an oil-water emulsion the content must be increased to above 0.01 per cent.  In hot rolling the compound is mixed with the coolant or lubricant supplied to the pass. Good results are obtained by adding 0.3 to 1 per cent of NaBF4.  The compound may be added to an aqueous emulsion containing from 1 to 10 per cent of at least one substance selected from the class consisting of lubricants and surface active agents, preferably wetting agents. Examples of surface active agents are: monoethanolamine oleate, sodium oleyl sulphate, ester of oleic acid and sodium aminoethyl sulphonate, sodium oleyl sulphonate, ceryl benzene sulphonate, cetyl pyridinium chloride, glycerol monostearate.  When an aqueous coolant is used, the preferred compound is an alkaline fluoborate, or zinc, or ethanolamine fluoborate.  In extruding, dies and the walls which confine the metal behind the die are lubricated with a heavy oil or grease including the boron and fluorine-containing compound.

Title: Improvements in or relating to means for indicating and measuring vibrations in powered mechanical units
IPC: G01H9/00
Filed: 1942-01-20
Abstract: 553,518. Indicating vibrations. WILSON, H. E. Jan. 20, 1942, No. 795. [Class 106 (iv)] [Also in Group XX] Apparatus for indicating and measuring vibrations in powered mechanical units or other objects comprises a screen having pin-point perforations permitting the passage of light, means for rotating the screen, and means producing a magnified image of the paths traced by the light points when the apparatus is mounted on a vibrating body. As shown, a rotatable opaque screen 7 having perforations spaced along radial lines is housed in a tube 2 carrying a small voltage lamp and a reflector 5, at one end, and eyepiece lenses 11 at the other end. The screen 7 may comprise black paper between glass discs retained in a cell 8 by a screwed ring 9, and may be rotatable by a lever 3 secured to the cell and movable through 180 degrees in a slot in a ring 4 incorporated in a stand by which the apparatus is supported on the object under test. The perforations are equally spaced along any one radius, but differently spaced in different radii, and the radii extend over a quadrant of a circle so that any of them may be rotated into any angular position. In use, the screen is rotated until the perforations in one radius are moved by the vibration in the direction of the radius and their paths appear to form a continuous line without overlap of the paths ; the screen position then indicates both direction and amplitude of the vibrations.
